What is the physical meaning of wavelength of object?

In: Physics

Objects don’t have wavelengths, only waves do. Waves can move through physical mediums (like ripples through water), or they can be part of a phenomenon like electromagnetic radiation — where the wave is a sort of physical effect that drives its own motion and does not have to be travelling through anything at all in order to move. In either case, the wavelength is the distance between two peaks (or two troughs), ie. it is the smallest repeating unit of a wave.

If you meant what is the **wavefunction** of a physical object, well…. that’s a whole different thing which is firmly within the realm of quantum physics.

Wavelength of an wave simply means length of a wave. It is distance between two consecutive peaks of a wave.

Apparently, waves looks like a long object with transverse shape. Different radiations like infrared, light have different sizes of their waves but same pattern of shape which is transverse. So, to know the length of a single wave in a waveform, we use the term wavelength which is different for all types of waves ( of light, infrared, or gamma rays ). For example, wavelength of visible light wave is 380 to 700 nm and wavelength of infrared wave is 700 nm to 1mm.
